Hi all,
I've been trying to use the CAS proxy mode with Liferay Portal, so that a
portlet can use the portal to authenticate a CAS protected service. I set
the ProxyTicketReceptor servlet in the web.xml. This works great if the
protected service is for example a Java Web application, protected with the
CAS filter.
Nevertheless, I noticed the ticket provided by the
ProxyTicketReceptor.getProxyTicket method (which I'm using in the portlet)
begins with ST. I thought this ticket would be a proxy ticket and so would
begin by PT. I then encountered problems if my protected services is for
example a PHP application, using the PHP CAS API. I get the following error:
<cas:authenticationFailure code='INVALID_TICKET'>
Ticket failed validation specification. Possible errors could
include
attempting to validate a Proxy Ticket via a Service Ticket validator, or not
complying with the renew true request.
</cas:authenticationFailure>
It seems the PHP CAS client tries to validate the ticket as a service
ticket, but notices that it does not fit. The result is that the
authentication fails.
Does anyone know if I'm misusing the ProxyTicketReceptor servlet, as it does
not generate a proxy ticket?
Thanks all.
